Clarke will play Reinhard Heydrich, the highest-ranked Nazi officer who was considered to be the mastermind of the ‘Final Solution’. He was assassinated by two resistance paratroopers (to be played by O’Connell and Reynor) in 1942, paratroopers personally selected by Winston Churchill and President of Czechoslovakia Edvard Benes.

Pike will play Lina Heydrich, an aristocrat married to Reinhard and who reportedly introduced her husband to the Nazi ideology. Wasikowska will play a Czech resistance fighter.

David Farr, Audrey Diwan and Jimenez adapted the script from Laurent Binet’s first novel. Alain Goldman and Simon Istolainen will produce. Shooting will begin in Prague and Budapest in early August.
